The proton spin–lattice relaxation time T1 and the nuclear magnetic resonance second moment were used to study the molecular dynamics of 1,2-O-(1-ethylpropylidene)-α-D-glucofuranose, a new low-molecular-weight organogelator, in the temperature range of 85–308 K. The observed T1 minima were attributed to the motion of methyl groups. The experimental data were interpreted in terms of Haupt's theory assuming the tunneling-assisted relaxation process.
